IMPROVED MOP-HEAD.

@In dgrhulr Infant in in ilgrse tnttrs ntrut ma uniting :gmt nf tigesuur.

TO ALL WHOM IT MAY CONGERN:

Be it known that I, O. S. GARRETSON, of the city of Cincinnati, in thecounty of Hamilton, and Stat-o of Ohio, have invented a new and usefulimprovement in the construction of Mop-Heads; and I do hereby declarothat the following is a full, clear, and exact description thereof,reference being had to the accompanying drawings, making a part of thisspeciication, in which- Figure 1 is a perspective view of the head witha part of the handle attached, the parts being vput together complete.

Figure 2 is an elevation of the same, part of the nut and part of thecollar of the loosejaw being removed to show the manner in which theflange of the nut enters thc collar, and, by being rotated, acts on thescrew of the shank or handle, and makes the loose jaw recede from orapproach the fixed jaw or cross-head; also the manner of connecting theparts of the loose jaw together.

Figure 3 is a perspective view of part of that part of the loosejaw thatforms the collar broken in two to show therecess in which the flange ofthe nut plays, and the recess designed to receive and retain the smallerparts of the same, or that part that may be formed of wire, as hererepresented, with the holes by which with rivets the parts are securedtogether.

Figure 4 is the nut shown in perspective.

Like letters indicate corresponding parts of all the gures.

My improvement in mop-heads chiely consists in constructing that part ofthe loose jaw that forms the collar in two parts or halves, with theinner surfaces properly grooved to receive and retain the flange orwings of the nut, and to allow it to have a free rotatory motion, bywhich means the parts with the recesses and rivetholes may be castcomplete, requiring no drilling or reaming in putting together.

As represented in fig. l, a a is the xed jaw or cross-head, and is easthollow to receive the handle 7L. In fig. 2 the loose jaw is marked I cc; and here one part of it, marked c c, is removed, the better to showthe recess in which the ange of the nut d d plays. Part of the nut isalso removed to show how the thread of the screw on its inner surfaceacts on the screw on the shank or handle 7L, and the flange is retainedin the recess in the loose jaw, when, by rotating the nut by thethumb-pieces g g, fig. 4, the loose jaw b Z c c must recede from orapproach the fixed jaw, for the purpose of receiving and retaining themop. Fig. 4 is the nut, shown in perspective, with one thread of a screwvon its inner surface, to match the screw on the shank or handle L, withits thumb-pieces g g, by which it is rotated. Part of the flange on itsouter surface is also lacking, better to adapt it to beV moulded andcast without coring.

The important advantage gained by my construction of the mop-head isthat, by constructing that part of the loose jaw that forms the collarfor the nut in two parts or halves, it, with its recesses andrivet-holes, may be cast complete, and will require no drilling orreaming in putting together, a great saving of labor in constructing,and when done forms a neat, compact, and durable article.

The operation or manner of using it is to turn the nut by itsthumb-pieces g g, g. 4:, and the loose jaw recedes from the fixed jaw orcross-head, and the mop may be inserted. Turning the nut in an oppositedirection brings the loose jaw and the cross-head near together, and themop is held firmly in position.

What I claim as my invention, and desire to secure by Letters Patent, is

Making the collar of the loose jaw in two parts, so that the nut d d maybe placed between them ;A and, when connected together, the collarsurrounds the nut and retains it in position, for the purpose above setforth.

In testimony of which invention I hereunto setmy hand..

O. S. GARRETSON.
